Attachment download or preview sits at zero(0) percentSupport

Hi All - I am using the native samsung email client configured through MDM. When I click on attachments and choose either preview or download it just sits at zero percent. I never receive an error. I have 4.2.2 and a Verizon S4. We have seen this issue on a few Galaxy devices world wide. I have checked all the defaults and I do not see anything for the email client. We are using MDM and controlling aspects of attachemnts. Typically it is opened in then thinkfree attchment viewer.

Im having exactly the same problem. Have seen other s4 set up the same that dont have this problem. My IT department havent got a clue and no one on here seems to know either. Have you fixed this problem yet??
